Śrīmad-Bhāgavatam · Text 11.9.4
Who is speaking and story frame
द्वावेव चिन्तया मुक्तौ परमानन्द आप्लुतौ ।
यो विमुग्धो जडो बालो यो गुणेभ्य: परं गत: ॥ ४ ॥
dvāv eva cintayā muktau
paramānanda āplutau
yo vimugdho jaḍo bālo
yo guṇebhyaḥ paraṁ gataḥ
In this world two types of people are free from all anxiety and merged in great happiness: one who is a retarded and childish fool and one who has approached the Supreme Lord, who is beyond the three modes of material nature.
